Mistakes when playing as Humans.

try this tactic: take Vittorio, and in the beginning, upgrade the ballista to three shots, and add the tent to the machine management skill. If you encounter light magic, take it. Upgrade the guardian angel. Then, wait for leadership. Max out the empathy skill. The hero turns out to be quite good. Humans already have powerful units. After that, you can choose any skill you like, preferably one that improves defense, because you can always attack, but it's not always possible to withstand an attack.
